Features & Advantages

Two in one offer that gives value for your money. Hydra Crystal clears green water and Bio Aquatic Bacteria restores your pond’s ecological balance by boosting the growth of beneficial bacteria.

Hydra Crystal

  • Hydra Crystal is safe to use in water with fish. It poses no danger to birds, invertebrates, reptiles, aquatic plants, mammals and humans. Ideal for use in farm ponds or garden ponds with koi or goldfish.
  • Hydra Crystal effectively flocculates scattered algae, causing them to sink and mopped up by filtration system. The result is clear water.

Bio Aquatic Bacteria

  • Once the existing growth of algae is eliminated, Bio Aquatic Bacteria balances the pond water chemistry.
  • Beneficial bacteria can help to reduce ammonia levels. In addition, they digest excessive nutrients that cause poor water quality and act as a food source for algae and weeds.


The Problem

Pond hobbyists often have to tackle Green algae growth in their ponds at one time or another. Despite all efforts to keep the pond water clear and fish healthy, sometimes the ecological balance of the pond water is disrupted. Algae removal treatments may effectively remove algae but are unable to stop it from returning. It is important to fix the root cause of the problem.

The Solution

Hydra brings you an economical Combo Pack: Hydra Crystal + Bio Aquatic Bacteria. The pre-selected products ensure complete eradication of the algae and protection from future infestations. The combo pack not only gives you the value for your money but also offers you the perfect combination of products for complete pond and garden care.

Cleared green water in just 1 day
25 September 2022  | 

Excelent product and service, I had green water in my koi pond due to a blown uv bulb, the water was like lime cordial but after using the combo pack of hydra crystal + bio aquatic bacteria the water was clear after just 1 day.
Can't believe these products worked so quickly, it's a miracle. I will use more hydra water treatments from now on.
